The professional way is to get the point spread function from each one using dynamic psf and perform an individual deconvolution on each layer. Looking for devices featuring ED glass and double lenses will help to combat the CA and make your images crisper with truer colors.You are a OSC imager, right? If so, use the split channels command to create three individual mono frames. Color fringing can cause frustration when you are zoomed in on wildlife in the distance. Conclusion At the end of the day every optical device, monocular and binoculars included, suffer from some level of chromatic aberration. If you are using your device at dawn or dusk when the ambient light isn’t as intense, CA will not appear as severe. If you are looking into the bright sky you may experience more severe CA. Technology aside, if you aren’t able to look past the chromatic aberration, a possible fix is to avoid high-contrast imaging. This glass will decrease the span of the color wavelengths, thus minimizing the lenses’ ability to produce chromatic aberration. In addition, CA will often be minimized by monocular and binoculars that utilize extra low dispersion glass, or ED glass. The result we see is the apparent cancellation of the other’s CA, though these results aren’t always flawless. These lenses are made of two different types of glass and fastened together. To help us combat this problem, most devices use achromatic doublets, or simply double lenses. This however isn’t the case when you are using a monocular or binoculars in real time.

In the case of pictures from cameras, the CA can often be corrected by using computer software after the picture is taken. How Do I Fix Chromatic Aberration? The effects of Chromatic Aberration can often be difficult to correct. Every device has a different severity of CA, so it is not one size fits all. If you see color fringing around the border of this object, whether it is green, red, blue or some combination, your device has CA. An example of a scenario that will make this process easier may be looking at a tree or object with a bright sky in behind. How Do I Know If My Device Has Chromatic Aberration? The best way for you to determine if your optical device has CA is by performing a test in a high-contrast scenario. The color fringing, in this case most often purple and blue, will only be seen around the edges of your image. With Lateral CA, the effects are not seen on the image in focus. Lateral Chromatic Aberration Lateral Chromatic Aberration occurs when color wavelengths intersect correctly, but not at the right location on the focal plane. This fringing could be red, blue and/or green. This fringing can even appear in the center of the image, as well as portions that are out of focus. With this type of CA, you can expect to see fringing around objects in your view. Axial Chromatic Aberration Axial Chromatic Aberration is the result when the wavelengths from the lens do not converge on the focal plane at the same location. Generally speaking, CA is classified as two different types, Axial and Lateral. In a perfect world, these wavelengths will intersect at the focal plane and produce a crisp and correctly colored image to you. This will create unclear, blurry, or discolored images. This tricky problem results in the inability for colors to combine at the focal point. Another issue may be your lens cannot transport the wavelengths to the focal plane at all. Chromatic aberration occurs when your lens cannot intersect all color wavelengths to the same location on a focal point. It is also referred to as color fringing due to the apparent color abnormalities you will see in your image. What is Chromatic Aberration? Chromatic Aberration, or CA, is a problem you will face with any and all optical devices. But what exactly is happening? What causes it, and how can you fix it? Let’s find out.
The real test for your instrument is in its ability to minimize the effects we see. It can be extremely frustrating and, if you aren’t sure what exactly is happening, may lead to you cutting your viewing short. In reality, this issue happens to every single device on the market.
This is more technically known as chromatic aberration. When you are using your monocular or binocular, you may be wondering, why do the edges of the view look discolored? Or perhaps you notice the objects you’re viewing look fuzzy and have fringing.
